1 LOCK-STRIKE.

Specification of Letters Patent.

Application filed March 14., 1912. Serial No. 683,803.

To all whom it may concern:

Be it known that I, JOSEPH A. DUPUIS, citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Lock-Strikes,

of which the following is a specification.

This invention relates to lock-strikes, and has for its object toprovide a lock-strike of simple construction which may be readilyreversed so as to adapt it for use in connection with locks applied todoors opening either inwardly or outwardly.

One aim of the invention is to provide a lock-strike which may not onlybereadily reversed or applied to a door-jamb to serve as a keeper for alock carried by a door opening either inwardly or outwardly but may alsobe adjusted to adapt it for use in connection with different types oflooks.

A further aim of the invention is to provide a lock-strike soconstructed that it may be readily adjusted after having been applied-to a door-jamb, so that it will serve effectually as a keeper for thelock in connection with which it is used, even should the door settle orsag considerably.

In the accompanying drawings :-Figure 1 is a view in side elevation ofthe lock-strike embodying the present invention. Fig. 2 is a perspectiveView illustrating the adjustable plate of the strike. Fig. 3 is asimilar View illustrating the attaching or body-plate of the strike.Fig. 4 is a horizontal sectional View on the line 4-4 of Fig. 1.

Corresponding and like parts are referred to in thefollo-wing'description and indicated in all the views of theaccompanying drawing by the same reference characters.

In the drawings the body or attaching 'plate of the strike is indicatedby the numeral 1 and is illustrated as flat-sided and formed at each endwith an opening 2 for the passage of securing screws (not shown).

The plate 1 is formed in each side with a shallow recess 3 and theformation of these recesses results in a web 4 which constitutestheintermediate portion of the plate. This web l'is formed with arelatively wide slot 5 which terminatesat its end short of the end wallsof the recesses 3 and is of a width slightly less than the recesses 3.An open-' ing 6 is formed through the web 4: immediately beyond each endof the slot 5 and the walls of the openings 6 are threaded fora purposeto be presently explained. The

plate 1 is formed at one lateral edge with the usual tongue 7 againstwhich the end of the latch-bolt of the lock is to strike, but thistongue differs from the ordinary tongue in that is beveled upon oppositesides as clearly shown in Figs. 3 and 4 of the drawmg. i

The plate 1 is adapted to be applied to a door jamb with either sidedisposed against the jamb as will be readily understood depending uponwhether the -door is mounted to swing in or out, and in connection withthe plate 1 there is provided a plate 8 in which there are formedopenings 9 and 10, the former being of a size to receive the end of thelatch-bolt of the lock in connection with which the strike is used, andthe latter being proportioned to receive the end of the lock-bolt. Oneface of the plate 8 is formed with a recess 11 located between theopening 9 and the upper end of the said plate and with a similar recess12 located between the lower end of the opening 10 and the lower end ofthe plate. The bottom wall of each recess 11 and 12 is slotted as at 13,the slots being of less length and width than the said recesses.

The screws 14: are inserted through the slots 13 after the plate 8 hasbeen disposed within one or the other of the recesses 3 in the plate 1with its opening 9 located opposite the tongue 7 and these screws arethreaded into the openings 6 in the web 4 and after the plate 8 has beenproperly adjusted, are tightened, so as to hold the same at' adjustment.

From the foregoing description of the invention it will be readilyunderstood that the plate 1 may be applied to a door jamb with eitherside resting against the jamb and that the plate 8 may be adjustablysecured in Patented Apr. 22, 1913..

either recess 3 of the plate 1. It will also be understood that shouldthe door sag or settle so as to bring the latch and lock bolts of thelock carried thereby out of position to properly engage in the openings9 and 10, the plate 8 may be adjusted up or down so as to provide forsuch engagement.

Having thus described the invention what is claimed as new is 1. A lookstrike comprising an attaching plate formed in opposite sides withrecesses, and a plate adapted to be interchangeably seated in therecesses, and means for holding the second mentioned plateat adjustmentin y the recess in which it s seated.

' 2. A lock-strike comprising an attaching plateformed in op osite sideswith recesses,

a plate adapted to e interchangeabli seated in the recesses, and meanssecurm 't e plate, in the recess in which it is seate the said plate bng formed with a bolt-receiving opening." I o v 3.'A; loclnstrikecomprising an attaching ceiving opening, and means for holding the lastmentioned plate at adjustment vin the 15 recess in whichitis' seated,the opening in the said last mentioned plate being in registrationwiththe slot in the first mentioned plate. 7
